No air blow- Heidelberg Windmill 10x15

I can’t seem to get any air to separate the sheets when running. All the adjustments are wide open, airlines have recently been cleared.

Machine is a 1960 Heidelberg Windmill 10x15.
Please help.

Clean the pump valve with parrafin or some non aggressive spirit cleaner , the one you screw in and out .Also clean the filter at the pump too .
When running you do not need the delivery valve blower right open so close it for a start and that will give you more blow at the feeder , having the seperator blowers too low has an adverse effect with boards .
